[MPlayer-dev-eng] [PATCH] Add support for -m{arch,cpu}=pentium{3,4} in GCC 3.1

[Luca Barbieri]

GCC 3.1 supports pentium3 and pentium4 as arguments to -march and -mcpu
(it also supports pentium-mmx and several AMD processors, but it isn't
obvious how to detect them from /proc/cpuinfo).
We might also want to consider using the new optimization options like
-mfpmath.
